GAS-STOVE.

SPECIFICATION forming part of Letters Patent N 0. 255,912, dated April4, 1882.

Application filed December 29, 1881. (No model.)

I 0 all whom it may concern Be it known that I, JOHN H. BAUMGARD- NER,of Lancaster, in the county of Lancaster and State of Pennsylvania, haveinvented an Improved Gas-Stove, of which the followingis a full, clear,and exact description.

The object of my invention is to provide a new and improved gas-stovefor heatingpurposes.

The invention consists in a gas-stove constructed ofa series of tubesmounted on a base and provided at the lower ends with enlargements,these tubes containing a quantity of water, which is heated andconverted into steam by a gas-burner arranged below the enlargements ofthe tubes.

The invention further consists in parts and details of construction, aswill be fully described hereinafter.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal elevation of my improved gas-stove, partsbeing in section. Fig. 2 is a plan view of the same, parts being brokenout. Fig. 3 is across-sectional elevation of the same, showing the tubesbroken off.

A series of tubes, A, closed at the top and bottom, are secured in avertical position in the top of a box-shaped base or casing, B, thesetubes having an enlargement, 0, preferably made tapering directlybelowthe cover or top of this base B. An elongated Bunsen or atmosphericburner, D, passes longitudinally through the base B below the enlargedparts 0 ofthese tubes. ThetubesAmay be arranged in a single, double, ormultifold line, either straight, angular, or circular, as may bedesired; and any desired number oftubes may be united on a base orcasing, B. I prefer to arrange these tubes A in two parallel rows, withthe burner D below and between these two rows, the burner-aperturesJbeing so arranged that an outwardly-inclined flame, K, will strike thebottom of each enlargement G of the tubes A. The gases of combustionpass out of the casing or base B through an opening or short tube, L,and may be permitted to escape into the room or may be conducted to aflue. Each tubeA contains a quantity of water, M, and in the rest of thetube thercis'a vacuum. This vacuum isobtained by raising steam in thetubes until this steam escapes through an aperture, 0, in the top ofeach tube. Then the apertures O are closed by close-fitting plugs N, andwhen the steam condenses a vacuum is created in each tube. This vacuumcauses a much more rapid production of steam, and the stove will thusheat very rapidly.

The cluster of tubes A is preferably covered by a top plate, or screenand top plate, in the same manner as steam-heating radiators arecovered.

Having-thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In a gas-stove, the independent watertnbesA, constructed, substantially as herein shown and described, withenlargements O at the lower end, as set forth.

2. The combination, with the casing or base B, of the independentwater-tubes A,providcd with enlargements C at the lower ends, and of theburner D, substantially as herein shown and described, and for thepurpose set forth.

3. The combination, with the casing or base B, of theindependent vacuumand water tubes A and the burner D, substantially as herein shown anddescribed.
